The former Brazilian leader has been taken into custody after authorities found he posed a serious risk of fleeing while under house arrest.
The former head of state was convicted of orchestrating a government overthrow in September and given more than 27 years in jail, but he was staying under confinement pending appeals.
Brazilian Supreme Court Justice the presiding justice said the move to detain the septuagenarian politician was a precautionary step after fresh information were revealed.
This included attempting to break his electronic bracelet and a invitation to a public vigil that could "allow for a possible escape.
Legal Document Reveals Flight Fears
In a paperwork permitting the detention, the judge said intelligence from the centre monitoring the former president's confinement suggested the ex-president's aim to disable the electronic ankle bracelet to secure accomplishment in his getaway".
This, it said, would be assisted by the confusion caused by the demonstration called by his offspring.
His son, Flávio, who serves as a congressional representative, called for a meeting of his backers near his father's house to take place on Saturday night.
The senator wrote on digital networks on Friday: Will you battle for your nation, or watch it all from your mobile device there on your sofa? I call on you to struggle with us."
He said the vigil would be so supporters could seek divine intervention for his well-being and for the reestablishment of democratic governance in our nation."
Diplomatic Refuge Fears
Part of the judge's decision was the chance of his transfer to foreign missions near the home, considering that the inquiries revealed a background of planning to request asylum through a consular facility", a announcement said.
The judicial paperwork highlights that the American diplomatic mission in the national capital, the capital city, is positioned around approximately 13 kilometers from Bolsonaro's home.
Worldwide Consequences
His judicial problems have generated frustration from fellow right-wing populist United States President Trump, prompting him to enact a half-rate duty on Brazilian product imports.
Bolsonaro is being kept in a Federal Police station in Brasilia and will experience a custody hearing on Sunday.
Latest Court Petitions
It was only on Friday that the his legal team asked the Supreme Court to allow him to fulfill his full incarceration period under domestic detention, with electronic monitoring.
They also petitioned that the former president be allowed to depart his residence for medical treatment, saying he required ongoing care for pulmonary infections and other health problems.
Background on Conviction
The former president was determined responsible of leading a conspiracy aimed at retaining his authority after he failed to win the national vote to his political opponent, President Lula.
High Court judges said that he was aware of a plot which involved plans to murder the current president and his vice-presidential running mate, Alckmin, and to detain and kill the presiding judge - the top judicial official who has been overseeing the former president's case.
The plot was thwarted because it didn't receive the support of the armed forces officials. Lula was inaugurated without incident on 1 January 2023.
But a week later, on January 8th, thousands of his backers stormed and vandalised official structures in the capital, Brasília.
The police intervened and around approximately 1,500 persons were detained.
The magistrates found that the protesters had been encouraged by him whose plan, they said, was for the country's army to step in, bring back stability and bring him back to power.
At the moment, the legal team called the 27 years and three months sentence extremely harsh.
He was also banned from seeking elected position until 2060 - a decade minus two years after the conclusion of his imprisonment.
The ex-leader called the court case a political persecution and said it was designed to prevent him participating in the next presidential race.
